Information Technologies of Automation of Motor Grader Control in the Soil Processing with Changes of the Capture Angle of the Blade

Based on the consideration of the existing difficulties with the control of the working process of the motor grader, a system of automatic control of the working body of the motor grader according to a parameter characterizing the efficiency of the working process while providing the high quality of the surface obtained after the passage is proposed. The algorithm of automatic control of the capture angle of the blade of the motor grader in the process of cutting and moving the soil along the parameter characterizing the current productivity is presented. An imitating model of the motor grader's work was developed for cutting and moving the soil with the proposed automatic control system for changing the angle of capture of the oblique blade of the motor grader. Investigations were made and the results of estimating the spread of the widths of the resulting web of the finished soil surface were obtained, on the basis of which conclusions were made about the possibility of using the developed automation system of the motor grader working process in the construction industry.
